3.2v 35.1ah 112.32wh Module with 26x 18650 Lifepo4 Cells
Here are battery modules with 26x 3.2v 1350mah cells in parallel. Each module is resting around 3.3v and total capacity of each module is around 35.1ah. These batteries were not used however it seems like some of the welds may have been weak and that's why they were never actually used. At this price, getting 26x 18650 3.2v cells for just 50 cents each is a great deal. Even if you have to remove the cells and use them for another project.
Below is the datasheet for the single cells. Of course these cells have a shrink wrap instead of cardboard wrap but the specs are the same.
